I went to open a midi file I emailed to myself from Chordbot and only got the option to open it in NLog Midi. I'd love to see a Thumbjam option come up when I click to open a midi file. Is that feature coming?

That feature will eventually show up in TJ, but probably not for a little while. The other end of that will probably show up first, where the midi for a loop you record in TJ can be opened in other apps (or emailed).... since it can already be saved and exported with a loopset now.
